循环流化床锅炉主要的磨损部件及防磨措施

Major abrasion parts and anti-abrasion measures for circulating fluidized bed boilers

循环流化床锅炉中金属部件及耐火材料的磨损是造成其运行事故的主要原因之一。因此,循环流化床锅炉中金属部件和耐火材料的防磨措施,直接影响循环流化床锅炉机组的经济运行和安全运行。为此,介绍了循环流化床锅炉主要金属部件及耐火材料的磨损及其产生磨损的原因,提出对不同的磨损位置及耐火材料,应采取不同的防磨措施。

The abrasion of metallic parts and fire-resistant materials for circulating fluidized bed (CFB) boilers is one of the main causes of operation failures. As a result, corresponding anti-abrasion measures are of great importance. This paper analyzes the abrasions on major metallic parts and fire-resistant materials for CFB boilers, and suggests the use of different anti-abrasion measures according to different situations.
